DEVICE FOR TRANSPORTING LOADS.

Specification of Letters Patent.

Patented Jan. 24, 1911.

Application filed January 6, 1910. Serial No. 536,690.

To all whom it may concern:

Be it known that I, HEINRICH OTTO ADAM, a citizen of the German Empire,residing at 37 Uhlandstrasse, Dresden, in the German Empire, haveinvented certain new and useful Improvements in Devices for TransportingLoads, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to an improvement in the apparatus for conveyingloads especially suitable for use in coaling ships, described in myprior specification of Letters Patent of the United States No. 840,099.In the apparatus therein described there are employed, for the purposeof attaching the loads to the haulage-rope flexible supporting links,such for instance as slings, which are destroyed when the load arrivesat its destination. In arrangements of this kind the conveyance of theloads takes place between a pair of pulleys.

With the present invention the rope carrying the slings may travel overor underneath any suitable number of pulleys without causing an unduetwisting of the rope and without interfering with the loads dependingfrom the slings. For this purpose, the pulleys are so pivoted to theirsupporting brackets that they adjust themselves au-.

tomatically to the direction of the pull exercised by the rope, whilesuitable sling deflecting devices prevent any undue interference betweenthe pulleys and the loads carried by the slings.

In the accompanying drawings: Figure 1 shows diagrammatically inelevation the arrangement of the pulleys for guiding the ropes when coalis to be conveyed from a transport ship to a man-of-war. Fig. 2 is aplan View of the arrangement shown in Fig. 1, and Fig. 3 is a transverseview of the same. Fig. l is a side view showing the method of suspendinga rope pulley to oscillate; Fig. 5 is a front view of the same; Fig. 6shows a device for deflecting the load when the sling carrying it passesover a pulley and Figs. 7 and 8 are respectively a side View and a planof the deflecting device. Fig. 9 shows a modified form of carrying theinvention into practice wherein a separate deflecting device isdispensed with; Fig. 10 shows a special form of deflecting device havingin side elevation a horn-shaped projection; Fig. 11 is a front view ofthis arrangement showing atthe same time the slight projection of theedge of the pulley; Figs. 12 and 13 show respectively in side and infront view a place at which the pulley mechanism is loaded; Fig. 14shows diagrammatically the arrangement for taking off the loads by meansof which unloading may be effected at various places; and Fig. 15 showsan arrangement of devices for destroying the slings at the pointsdesired.

The drawings by no means exhaust the possibilities of this invention,which may be modified in any suitable manner without departing from thefundamental principle thereof.

In Fig. 1, a indicates the transport and I) the man-of-war. Both shipsare provided with masts or other suspension devices which carry thepulleys [L2, 70,, k and h other ulleys h, 71,, 7b,, h, and h, beingarrange in suitable positions, for instance on deck or in the hold. Overthese pulleys there runs a haulage rope 0, 0,, 0 etc.; the loads to beconveyed from the transport a to the manof-war Z) are indicated by fwhile f indicates the receptacles to be returned from b to a. The loadsf and f, are attached to the rope mechanism by means of flexiblecarriers (Z, such for instance, as slings and the like.

Now the novelty of the present invention consists in the fact that therope may be guided at an angle not only in a single plane, but in anynumber of planes inclined to each other, without the pulleys interferingwith the loads and without the slings or the loads carried thereon beingcaused to wind themselves around the ropes in consequence of theirrotation. To-obtain this result, the pulleys, as is shown by way ofexample in Figs. 4t and 5, are suspended to oscillate in such mannerthat the groove for the rope may lie at any time in a plane determinedby two portions of the rope, as for instance, by the portions 0 and 0,.

In Fig. 4:, h is the pulley which is attached by means of the shackle rto the hook s. The shackle 7- may assume any position whatever inrelation to the hook s with the result that the pulley 72. can alsoassume any position in relation to s the position of this pulley at anymoment being determined by the position of the portions 0 and 0 of therope. This arrangement results in entirely eliminating all possibilityof lateral friction between the rope and the edges of the pulleygroovetogether with the consequentrotation of the ropes during the working ofthe apparatus. As new the rope can be guided to 8, projects beneath theconveying rope. in any desired manner it can of course also When thesling (Z With the load f comes be led for some distance horizontallyover close to the deflecting device, both the sling the deck and severalloading devices can then be arranged on it adjacent to each other. Forthis purpose there are arranged behind each other a number of sleeves aof the kind described in my aforesaid prior specification for thepurpose of conveying the slings on to the rope. With the constructionshitherto employed, these sleeves were made removable with the object offacilitating the passage of the slings of the sleeves behind them. Suchcontrivances are however not only very complicated and likely to causegreat waste of time, but they are also very dangerous as the remains ofthe slings that have been cut away and which are moving along with therope-ciio cuit, often cause the destruction of the body of the sling.

Now in accordance with the present invention the arrangement of severalsleeves is rendered practicable by so constructing them that they do notentirely surround the rope but only partially embrace it either fromabove or from the side to which effect the sleeves are ofsemi-tubularshape open at the bottom. Such sleeves as shown in Figs. 12and 13 are preferably movably suspended in such manner that the rope andthe parts carrying the loads can always pass them freely.

In Figs 12 and 13, n indicates the separate sleeves, (Z are the slingsand f the sacks of coal. The sleeves a are preferably guided by guidesa, and may bear by means of pulleys n on the rope c. The pulleys 01 bybeing slidably mounted on spindles 4a,, are capable of lateral movementif the rope should strikeagainst them. Should it happen, in theconstructions heretofore usual, that the slings should wind themselvesaround the rope, sleeves as heretofore constructed would on account ofthe apertures therein carry away the slings and the loads suspendedthereon. But the present invention renders the rotation of the ropeunobjectionable and therefore obviates this risk. The loading iselfected by the flexible slings d being placed upon several of thesleeves n and then attached to the loads to be carried. After the loadshave been secured in position the slings (Z are pushed away from thesleeves and are carried along by the ropecircuit. The loads now, asshown in Fig. 1, are brought beneath the pulley h, of the transport aand moved up to the level of the pulley 72. The guidance of the slings,that is to say, of the loads carried thereon over the pulleys 71, andIt, involves very consider- 7 able difliculty. Such a pulley over whichthe sling carrying the load is to be guided,

vice, the end of which, as shown in Figs. 6

and the load carried along by the rope 0 will be turned sidewise andduring the further rotation of the pulley will run in the groove thereofover the pulley in the manner shown by way of example in Figs. 7 and 8.As soon as the sling has passed over the pulley the load f will againresume its vertical position. The lateral deflection of the load mayhowever also be effected in such manner as to dispense with thedeflecting device Z, the pulley being caused to assume an' obliqueposition as shown in Fig. 9 so that the load suspended vertically uponthe sling (Z beyond the rim of the pulley and is kept by its weight outof contact with the pulley. But even when this arrangement is adopted itis advisable also to provide 'a deflecting device.

Figs. 10 and 11 illustrate a modified construction of deflecting device.Tn this case the lever arm Z is bent upward so as to form a horn andprojects upwardly from beneath the rope. This arrangement has the greatadvantage that no matter how high the speed may be, the load cannot comein collision with the pulley. Fig. 11 illustrates moreover a furthermodification of the method of guiding the pulleys, according to whichthe pulley on the side, on which the sling is suspended, has either norim whatever or only a very low rim, an arrangeient which affords greatprotection to the sling. To prevent the springing out of the rope fromthe groove of the pulley it there are provided guide pulleys p which arepreferably connected with the pulley h by means of a frame mounted tooscillate after the manner shown in Figs. 4 and 5, with the result thatthe rope pulley it together with the guide-pulleys p can assume anyposition suitable to the directions of the parts 6 and c of the rope 0.By this means it is rendered possible to convey the loads suspended fromthe rope 0 over the pulleys without incurring the risk that the slingswith the loads thereto attached will be drawn into the pulleys or becomeheaped up in front of them. 7

Just as the possibility of guiding the ropes in any desired mannerenables loads to be taken up at various places so in like manner itenables them to be put down at different points, their accumulation atany one point of the man-of-war being thus prevented. To this end thereis arranged either beneath or adjacent to, the hauling rope any suitabledevice for destroying the slings. This destroying device may be adjustedalong the length of the r0pe-circuit 0, being for instance movable inguides. linstead of employing one such device, which in that case mustbe movable, a number of such devices may be provided, these being putalternately into and out of action with the result that the loads arereleased at one time at the first, and at' other times at the second orthird positions, to be conveyed away by suitable chutes. Such anarrangement is shown in Fig. 15. After the load f has been separatedfrom the sling by the destroying device 11 it will fall upon the plate 2pivoted at w by which means the device 2) is caused to rotate about thepointy with the result that the subsequent loads may pass by it andreach '0 where they are released. The load f now falls upon the pivotedplate a which as it rotates about its pivot w causes by connecting rodv, the device 4) again to assume its initial position. By this means thedestroying devices 1) and o, are employed alternately. Figs. ll and 15illustrate the knives o and o diagrammatically and at right angles tothe position which they actually occupy. In other words, the knives aremade to swing in a horizontal plane on the vertical pivot y so that bytilting them laterally, the knives will be swung into or out of the pathof slings (Z. For the purpose of destroying the slings use may alsobemade of the variation of the direction of the hauling rope on a pulleyor of the surface pressure in a groove. By varying the speed of the ropeit is for instance possible so to increase the accelerating forces as todestroy either all the slings carried by the rope or a portion thereof.It is consequently also possible to effect the division of the loadswhen arriving on the man-of-war by adjusting for instance the speed ofthe rope in such manner as to enable a number of the slings to withstandthe strain due to the accelerating forces, while another portion isdestroyed. It is also possible to effect the division of the loads atthe unloading places by making individual slings either stronger orweaker than the remainder so that at the weak spots described only theweak slings are destroyed, while the stronger ones are carried to thespecial destroying devices.
